Document Summary
Types of management: (keep in mind: management means for human/economic use, not conservation: even aged management trees maintained at same age and size harvested at once and replanted cut present trees, then plant commercially desired monoculture low biodiversity not sustainable, uneven aged management uses selective cutting where not all trees are removed natural regeneration as opposed to replanting habitat is maintained high biodiversity sustainable. It is also important to note that once certain thresholds are met large scale changes will occur: eg. the difference between ice and water: breaking records for warmest year significantly year after year, what was frozen is now melting (sea ice, land ice, glaciers, permafrost, the sea level is rising (0. 1 0. 2m) in the last century warm water takes up more space so as it continues to warm the rise will increase as well the rate of melt is astronomical.
